injury from pressurized fluid, such as splashing
in the eyes or on skin, follow the Pressure Relief
Procedure when you stop pumping and before you
clean, check, or service the equipment.
1. Shut off the air supply to the pump.

Flush the Pump Before First Use

The pump was tested in water. If water could
contaminate the fluid you are pumping, flush the
pump thoroughly with a compatible solvent. See
Flushing and Storage, page

High/Low Lever

Use the High/Low lever to set the desired pressure
mode. When the lever is set to "Low," the fluid outlet
pressure is slightly less than the air inlet pressure.
When the lever is set to "High," the fluid outlet
pressure is slightly less than two times the inlet
air pressure. Note that the High pressure setting
increases both fluid outlet pressure and inlet air
consumption.
NOTE: The lever must be fully seated into the High
or Low position for proper operation.
